SPINNING-MULE.

SPECIFICATION forming part of Letters Patent No. 411,082, dated September 17, 1889.

Application filed November 7, 1888. Serial No. 290,231. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD WRIGHT, a citizen of the United States, residing at l/Vorcester, in the county of lVorcester and State of Massachusetts, have invented certain new and useful Improvements in Spinning-Mules, of which the following, together with the accompanying drawings, is a specification surficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

My present invention relates to improve ments in spinningmachines designed for spinning wool and similar fibrous material, the same being more especially adapted to that class of machines described in Letters Patent No. 370,8at0, heretofore granted to me, wherein the roving-drums and roving-delivering rolls are supported on a movable beam or carrier which travels toward and from the revol'ving spindles for giving the stretch when spinning and for winding the yarn upon the bobbins.

The object of thisinvention is, generally, to further improve and perfect the machine and to provide mechanism of superior efficiency and practical utility for the purposes intended.

The several features of my present invention and improvements are particularly pointed out and explained in the following description,the subject-matter claimed being hereinafter definitely specified.

It will be understood that some of my improvements may be employed in spinningmachines without the others, '16 in any case it is desired.

Fig. 21 is a side view of mechanism for starting the rovin g-delivery rolls before the roll-beam reaches its forward limit of movement. Fig. 22 is a front view of such starting devices, drawn to somewhat larger scale. Figs. 23 and 2 1 show an end view and section of the operatingwheel and ratchet employed in the starting devicefor the ro\ *ing-delivery rolls. Figs. 25 and 26 show modifications in the construction and manner of connecting the quadrantarm, quadrant operator, and cop building mechanism. Fig. 27 is a side view of a device for holding down the counter-faller while backing off and the train of gearing for operating the various shafts; and Fig. 28 is a section of the roll-beam and indicator, showing devices for operating the same.

In my illustrated machine the operating mechanism, disposed in as close and compact a manner as convenient, is located at a central position, while the spindles and roving- 5 drums are arranged on suitable frames that extend to the right and left from this central operating-head to a suflicient distance to accommodate the desired or given number of spindles. As this extension and multiplica- IO tion of spindles and drums will be well understood, only a few of the spindles are shown in the present drawings, in Fig. 1.

Referring to parts, A denotes the main frame, upon which are mounted bearings for supporting the various shafts and operating parts.

B indicates the back shaft, which extends throughout the length of the machine and is provided at intervals with sprocket-wheels B, carrying the chains l) ,bymeans of which the roll-beam or roving-drum carrier D is moved. forward and back.

(2 indicates the cylinder-shaft, which is also the driving-shaft and extends through the 2 5 operating-head of the machine, the band-cylinder 0 being coupled thereto axially in line at either end and together running the full length of the machine. The roll-beam I), having the roving-drums l) and roving-delivery rolls E mounted thereon, is supported by tracks or guideways a on the tops of the frame A, and is provided with suitable bearing-shoes that slide along said guideways.

b indicates the spindles,supported in the wcll-known manner along the front of the frame and rotated by bands Z), run from the cylinder 0, as usual.

Fallers fand counter-fallers f, of the usual construction, are provided for guiding the 0 yarn onto the bobbins, and said fallers are operated by the taller-lock F an d a cop-builder mechanism, which latter is of improved construction, as will be hereinafter explained.

The pulleys G G l for the driving-belt are arranged on the cylinder-shaft G. The pulley G is fixed or keyed upon the shaft 0. The pulley G, which is provided with a long sleeve or hub, runs loose on the shaft 0 and has a pinion G fixed to the end of its hub,

while pulley G runs loose upon the hub of pulley G and serves as the loose pulley on which the belt runs when the machine is idle. A large gear G is also m i unted e11 shaft 0, which is adapted to clutch with pulley G by means of afriction-rim, and isarranged to be thrown into and out of clutch by a lever actuated by one of the cams on the camshaft.

ll indicates the operator-shaft, I the camshaft, J the draft-scroll, and K the ill-drawing 6o scroll. The scrolls are respectively mounted on shafts J and K, and are connected by ropes and 7a to the drum-wheels or auxiliary scrolls and N, fixed on the back shaft 13, to which shaft; backward and forward rotative motion is imparted by the action of the respective scrolls for moving the roll-beam from and toward the spindles by the chains D The scrolls J and K are mounted to turn loose on their respective shafts, and are pro vidcd with clutches J 2 and K that connect them with their shafts for action, which clutches are operated by levers actuated at the proper time and in well-known manner bycams on the cam-shaft.

The various changes in the operation of the mechanism are automatically effected under control of the cam-shaft I and its automatic stop-escapement, giving live stopsor changes in its revolution; but as this cam-shaft and its m anner of operation are substai'itially si milar to that described in my former patent I i have not herein illustrated it in detail or particularl y described the form and location of the several cams thereon, since it will be understood that the same are of any suitable construction fm'in'lparting the action required for throwing into and out of engagement the several clutches.

L indicates the escapement-lever, bifurcated at its end and provided with hardened steel detcnts or lugs 11, that engage the ratchets of the cseapement-wheel l,and havingan arm L projecting from the side thereof, as shown. lly makin the escapement-lcver with the bifurcated head I am enabled to use an outside ratchet for the escapement-wheel and convenientlyobtain the five steps or notches, which, can be made with great facility, as the notches can be more readily filed to correct form, and also the t'Oll'lOVfLblO detents 7t can be given greater wearing-surface and be made in a manner to change position from one side to the other as the edges become worn, mak' ing a much more serviceable construction than where the escapement-ratchct works on a simple pin or dog and the ratchets are formed within a groove of the eseapementdisk. A spring-brake T1 is provided to act upon the arm L of the escapement-lever to retain it at position of adjustment.

The operator-shaft II and scroll-shafts J and K are rotated by a suitable train of gears. In this train of gearing (see Fig. 27) the gear G operates an auxiliary shaft Q, beneath the cylinder-shaft G by meshing into an intermediate gear Q, that in turn meshes with the pinion Q fixed on said auxiliary shaft. Said shaft carries a gear Q, that meshes with gear ll on the opwator-shaftll, which latter shaft carries the gear 11*, that meshes with the gear 1 on the cam-shaft I. The gear ll. on the operator-shaft meshes with the gear K" on the shaft K of the iii-drawing scroll K. The shaft Q is also provided with a gear Q, that meshes with the pinion G on the end of pulley G A pinion C tixed on the cylinder-shaft C, meshes with a gear V, mounted on a stud '2: on the side of the frame A, which gear carries a pinion \*',that meshes with a gear J" on the end of the draft-scroll shaft J.

The gear G is for backing off or reversing the motion of the cylinder and spindles preparatory to winding up the yarn, the mo tion being transmitted to said gear after it has been clutched to pulley G through the gears G Q Q and Q, while the belt is running on the second pulley G, substantially in the usual manner.

R indicates a rocker-shaft supported in bearings upon and near the top of the frame A and extending parallel with the guide a, along which the roll-beam D travels. Said rocker-shaft is provided with a series of fingers R R2 R that engage with a trip-piece d, connected with the roll-beam or roving-carrier and formed to crowd the fingers to one side as the rollbeam approaches the position thereof, and thus rock the shaft. Said rockershaft is also provided with a rigid arm or crank R, the outer end of which is joined by a link or rod Z with the horizontal arm L of the escapementlever L. The action of the rocker-shaft throws the detents of the escapement-lever L from engagement with the notches 0f the escapement-wheel I, thus allowing the cam-shaft I to shift the position of its cams for bringing into operation the different mechanisms, accordingly as the trippiece 01 strikes the respective fingers in the movement of the roving-carrier.

T indicates the twist-wheel, mounted on a swinging bracket T, that is worked in conjunction with a cam on the cam-shaft in wellknown manner for lifting said twist-wheel and causing it to engage for its operation with a worm-screw 011 the auxiliary shaft Q. Said wheel is provided with a pin 25, that moves into contact with a lug or projection T on the arm L of the escapement-lever L for throwing the detent h from the escapementwheel I when the proper degree of twist has been spun into the yarn.

The belt-shipper W is supported on a reciprocating rod 10 and arranged to be operated automatically by the lever W from a cam on the cam-shaft I or to be operated by hand by the lever V in connection with the inclined cam W on a rod W which extends along the front of the machine and is provided at intervals with suitable handles \V for turning it.

The take-up mechanism for returning the scrolls to position after the clutches are released, giving tension on the scroll-ropes, and compensating for the expansion and contraction of the ropes due to the variation in the degree of humidity of the atmosphere is a feature of my invention, and is made substantially as follows: WVinding wheels or drums J 3 and K are attached to respective scrolls J and K. To the peripheries of these drums a cord, strap, or band 0 is connected, one end being attached to the drum J and the opposite end to the drum K This strap passes over guide-sheaves O and around a sheave or pulley 0 which is connected with a spring 0 that presses downward the pulley O and thereby gives pressure simultaneously and uniformly at both ends of the strap, the sheaves or pulleys allowing the strap to adjust itself to the strain at either end and to the action of the respective scrolls when winding and unwinding their ropes, consequently giving proper tension on each of the scrolls one against the other and holding the ropes j and 7c uniformly taut at all times, while the yielding of the spring 0 compensates for any variation in the take up of rope by the scrolls or for any expansion or contraction of the ropes that may be occasioned by climatic changes. The sheaves O are arranged to run loose on a cross-bar or shaft at the back of the frame, so that they offer no resistance to the free action of the tension mechanism. In the present instance the spring 0 is arranged as a heavy wire coiled around a cross-bar A at the lower part of the frame, the center portion of the spring being extended backward and provided with a hook that engages the supporting-block of the pulley 0 The opposite ends of the wire are held by lugs on the bed-plate A. (See Fig. 16.)

One of the drums J 3 is preferably provided with means for taking up or letting out the tension-strap O, and may be constructed as indicated in Figs. 17 and 18. In this aratchet-wh eel J is fixed on the end of the scrollJ, while the drum J is arranged to turn loose on the hub of said scroll or its shaft, and a pawl J is pivoted on the side of the drum, that engages with the teeth of said ratchetwheel, it being held thereto by a suitable sprin g. By turning forward the drum while the scroll and its ratchet-wheel are held stationary the pawl slips over the notches and the strap is wound up more or less upon the drum and held from turning back by the engagement of the pawl. For letting out the strap or loosening the tension the pawl is lifted by means of a small lug that projects from its side, when the ratchet can be turned back the required number of notches and the pawl again allowed to drop into engagement for holding it at that position.

For connectingthe scroll-rope to the auxiliary scroll N, I employ an adjustable ropeholding device (see Figs. 12, 14, and 15) consisting of a collar or hub N having a rope grip or prongs n that adapt it for retaining the knotted end of the scroll-rope, which collar is arranged loose on the shaft B adjacent to the side of the drum or scroll N. The inner face of said rope-holder is provided with suitable notches or ratchets n, fitted for engagement with a lug n 011 the side of the scroll. The scroll-rope 7c is carried through a notch 71. on the rim of the auxiliary scroll Nand passed aroun d the peripheryof the rope-holder hub, its knotted end being inserted between the prongs 'n. The strain on the scroll-rope causes the knot to be drawn firmly into the recess between the prongs n, whereit is held fast, and also causes the rope-holder hub to hug against the side of the auxiliary scroll, so that the lug and notches on their adjacent faces engage, and thereby retain the ropeholder and rope end securely at position of adjustment.

If it is desired to lengthen or shorten the ropc,it can be done by simply sliding the ropeholder hub outward on the shaft B sufticiently to relieve the lug n from the notch n and. then turning the rope-holder on its axis to wind up or slacken the rope to the extent required, and then again allow it to be drawn up against the side of the scroll. This device affords a very simple and convenient means for expeditiously effecting adjustment of the scroll-rope, and obviates the necessity of retying the holding-knot at the end of the rope. The adjustable rope-holdingdevice, in

combination with the scroll and scroll-rope,

is a feature of my invention.

The improved arrangement of mechanism for controlling the delivery of; roving is as follows: On the shaft I there is a loose sprocket-wheel I, provided with a clutch 1, arranged to be thrown into and out of action by a lever actuated by one of the cams on the cam-shaft I. Said s n'ocket-wheel operates, by means of a suitable drive-chain p, a short shaft 1" at the back of the frame, provided with sprocket-wheels 1"", from which drivechains l extend to and around guidesheaves l near the front of the machine, said chains passing over and engaging with s n'ecket-whecls E iixed on the ends of the lower deliveryrolls E. The drums l), for supporting the spools of roving, are geared to receive their movement from the rovingdclivery rolls in the usual manner, (the gearing being at the ends of the machine, and in the present instance not shown.) During the time that the clutch I is thrown in and the sprocketavhecl l is in action the shaft l operates the chains l and the roving-delivery rolls are rotated for feeding off the roving; but when the clutch 1 is thrown off, the friction on the rolls E being greater than that on the other parts of the mechanism, the chains 1" are carried along with the sprocketwheels E without causing rotation of the rolls E, since the roll 1 and shaft l are at such time free to turn loose on their axes and are easily carried around by the lmckward movement of the chains 1.

In order that the entire stretch of twisted yarn may be wound onto the bobbins and that the succeeding draft may commence with the feed of roving full from the spindlepoints, I employ an auxiliary mechanism for starting the roving-delivery rolls an instant before the roll-beam l) reaches the forward limit of movement. This mechanism consists in the present instance of parts arranged substantially as shown in Figs. 21 to 211-. In this the sprocket-wheel E on the end of the roving-delivery roll E is provided with an internal ratchet 0, (see Fig. 24,) and adjacent thereto, mounted to run loose on the end of the roll-shaft, is a disk or wheel E", which carries a pivoted pawl e, that en gages the ratchet 0 in. a direction for turning the rolls E E forward. Upon the periphery of the disk E is wound a chain orband E one end of which is connected to the disk, while the other is connected to a swinging arm E, the upper end of which is pivoted to a standard 1)", fixed on the roll-beam l). Connected to and winding upon the hub of the disk E is a strap (Z", the outer end of which is attached to a spring I), as imlicated. This spring and the strap serve for returning the disk E and pawl e to normal position and for winding the chain E upon the disk. A suitable lug c is formed on the side of the swinging arm E and an adjustable stop-dog a" attached to the fl'ftll'l01\ for engagement with said lug.

In the operation, when the roller-beam approaches the spindles, the dog a", coming in contact with the lug c, arrests the arm E and can. draft upon the chain E, which effects motion of the disk, and the pawl c, by ongaging the ratchet 0, causes slight rotation of the roving-delivery rolls before the roll-beam reaches its forward limit of movement, thereby feeding off sufficient roving to reach from the rolls E to the points of the spindles S before the carrier or roll-beam changes its d irection of movement. \Vhcn the roll'beam is moved back, the arm E" is released from the stop-dog, and the disk, chain, and pawl are returned to their normal position by the action of the spring .1) and strap The disk E and arm E are held statiimary while the roving-rolls are operated by the chain l", the movement being then such as to carry the ratchet-teeth c of the wheel E past the pawl 13 without engaging it. This part ofmy invention, comprising the auxiliary starting mechanism forgiving fecdof roving before the starting up of the spindles, can be omitted in machines for spinning some grades of stock, if desired, or the devices can be made nonoperative by simply shifting the dog 1,1,so that it will not engage the lover or arm E. The machine will then run without the action of the auxiliary roving-feed. Usually, however, I prefer to use the auxiliary feed meclr anism, as above described.

The attaching-plate of the stop-dog is slotted, as at of, so that said dog canbc adjusted forward or back forgiving a longer or shorter arc of movement to the lever and pawl and a consequent variation of the amount of advance feed imparted to the rovings.

The auxiliary starting mechanism may be employed on only one of the lines of rovingdelivery rolls, as the rolls of the opposite line or at the other side of the operator-heml will be started by the power and motion transmitted from the iirstoperated wheel E through the chains l and sprocket-wheels 1.

An important feature of my invention consists in combining and constructing the copbuilder and quadrant mechanisms to operate automatically in conjunctionwith eachother, so that the devices for winding up the yarn and the devices forbuilding or giving shape to the bobbin are controlled by one set of mechanism or simultaneously adjusted. This feature I believe to be broadly new in spinning machinery. The mechanism is substantially as follows: The cop-builder mechanism is mounted upon a frame or carrier-bar 10,which is supported'by suitable bearings and provided with a toothed rack 9. Reciprocating motion is imparted thereto by a pinion 11,connected bya short axle with a sprocket-wheel 12, which is rotated alternately in one direction and the other by a drive-chain 13 from the sprocket-wheel on the back shaft B or by any equivalent mechanism that will impart to said carrier-bar a backward-and-forward reciprocating movement.

The rear bearing bolster or bed 8 is made with a flat surface, on which the bearing-boss of the carrier 10 slides, and this surface is surrounded by a channel and an upwardly-projecting flange 7, as shown in Fig. 6, thus forming a receptacle for holding a quantity of oil sufficient to cover the bearing-surfaces and give a constant and ample lubrication to the parts, which are in the action of the machine subject to great pressure at. certain stages of the operation.

The backward movement of the carrier 10 is performed during the time the yarn is being wound on the bobbin. A rotatable shaft 14, having the cop-builder-ad j usting screw and slide-adj usting screw 16 formed thereon, is mounted in bearings on the carrier 10, and the longitudinally-movable cop-builder plate 17, also supported on said carrier, is connected by a nut or threaded lug 18 to the cop-builder screw 15, whereby the plate is moved backward or forward along the carrier when the adj usting-shaft is turned in its bearings. The top edge of the plate 17 is made with a short level or straight portion at its rear end, forward of which is a long incline, which level and inclined portions serve as a bearing for the pin or lug 19, that supports the verticallymoving slide 20, which works up and down in suitable guideways on the carrier-bar, the slide being raised or lowered accordingly as the plate 17 is at forward or rearward adj ustment or at some intermediate position. The cop-forming bar 21 is hinged to the top of the slide 20, and in connection with the top surface of said slide forms the track on which the roll 00 of the cop-builder lever or arm X runs for raising and depressing the fallers. The hinge by which the bar 21 is connected to the slide 20 has its axis in line with the top surface on which the roll :1: travels, and is also at the junction of the backward and forward inclines, the backward incline being stationary on the slide 20, while the forward incline, which is on the bar 21, can be adjusted up or down. An adjusting stud or screw 23 is arranged in the top of the slide 20 beneath the forming-bar 21, by means of which the relation of the cop-forming bar can be adjusted for giving more or less inclination to its top surface. The hinging of the cop-builder bar in the manner described affords facility for Varying the winding at the point of the cone on the bobbin to make a longer or shorter taper in the winding without changing the other parts or without change in the winding at the shoulder of the bobbin.

A shaping-lug or cam-plate 22 is attached to the forward end of the builder-plate, and the front upper surface of said cam-plate, which is curved or inclined, is arranged to engage with a lug 21, that projects downward from the forward end of the cop-forming bar 21 for lifting said bar, and thereby regulating the length of the winding on of yarn at the base of the bobbin until the bobbin is filled to its maximum circumference. The curve or cam surface of thelug 22 is formed to give a rapid descent of the cop-forming bar at the commencement of the bobbin and then to gradually decrease the movement.

A stop-lug 24 is adj ustably fixed to the carrier for limiting the forward movementof the cop-builder plate 17, so that the attendant can at each doffing set the mechanism at the same position for starting the next set of bobbins.

The adjusting-shaft 14 has at its forward end a pulley 25, working loose thereon and carrying a pawl 20, which engages a ratchetwheel 27, fixed on the end of said shaft. A chain 28 passes over and is attached to said pulley, one end thereof being secured to an arm 29, pivoted to a fixed bracket attached to the floor or other stationary position,while a weight 30 is attached to its other end for rotating the pulley and taking up the slack of the chain when the carrier-bar 10 is moved backward. A sheave 31 is mounted on a suitable stud at the forward end of the carrier, which sheave runs onto the chain 28 as the carrier 10 moves forward, and by drawing down said chain partially rotates the pulley 25, at which time the pawl 26, engaging the teeth of the ratchet 27, causes partial rotation of the adjusting-screw shaft 14 and consequent adjustment of the parts connected therewith.

An adjustable incline or guideway 32 is attached to the carrier 10 and works on a horizontal pivot, whereby it is adapted to assume different degrees of inclination, its rear part being sustained by an adjustable support or hinged brace 33 in connection with a slide -block 34, that moves longitudinally upon the carrier-bar, on which it is confined by suitable guides. The slide-block 34 is screw-threaded, as a nut, to en gage the threads 16 on the end of the adjusting shaft 14, by means of which said slide-block is movedforward and back for raising and depressing the rear end of the hinged guideway 32. The slide block 34 can, when desired, be adjusted to move past the dead-center or beyond the position at which the brace 33 stands vertically, (see dotted lines in Fig. 6,) so as to slightly lower the inclined guide 32 after it has reached its highest position.

The screw-thread 15, that moves the copbuilder plate, is conqiaratively line in proportion to the screw-tlu'cz'ul it; at the end of the shaft, the former having a pitch of about eight to the inch, while the latter has a pitch of aboutthree to the inch, (more orlcss.) (,.on Sequently the slide-block is moved much more rapidly than the plate by a given revolution of the shaft. The serew-thremls 16 arcof less extent along the shaft than are the threads 15, as well as of greater pitch, so that the nut or slide-block 3t run s off from the end or threaded portion of the shaft, and its backward movement ceases at an early stage of the operation, the limit of such action corresponding to the time of forming the base-cone of the bobbin,while the thread it") continues to move the cop-builder plate until the bobbin is tilled.

A red 35, connected to the cop-builder plate 17, extends backward through an opening in the slide-block 3t and has upon its screwthreaded end beyond the slide-block adj usting-nuts 351, as indicated. Said rod serves for drawing the slide-block forward and into engagement with the screw-threads on the end of the adjusting-shaft when the copbuilder plate is moved to its forwardposition. The adjustment of the nuts on the end of this rod 35 preferably such that when the copbuilder plate 17 is moved forward, so that. the junction-point of its incline and level top is beneath the pin 10 on the vertically-moving slide 20, the slide-block ill will be at a position where its scrcw-threzuls will commence to engage the screw-threads 16 on the end of the shaft.

The end of the adj usting-shaft it is sq uarcd or fitted to receive a wrench or handle for running the (am-builder plate and inclined guideway back to their first or starting positions after a set of bobbins has been tilled and preparatory to commencing a new set of bobbins.

An arm or lever 4-0 is fulerumcd upon an axis near the back of themachine (in thepresent instance upon the back girt or red A, that connects the frame A) in a manner to swing back and forth. On its lower part said arm carries a pulley t1,revoluble on a suitable stud, which is preferably secured in a slot in the arm, so that the pulley can be adjusted nearer to or farther from the axis on which the arm swings. This adjustment is for the purpose of making cops or bobbins of larger or smaller diameter, adjustment toward the center or axis on which the arm swings giving a smaller diameter of bobbin, and vice versa. No change in the position of the pulley-stud is made except it is desired to change the machine for running bobbins of a different size. The lever l0 serves a purpose similar to that of thcpart which in others linningmachines is known as the quadrant, and I will therefore term it the quadrant-arm, although the construction and operation are quite different from quadrants as heretofore employed.

Combined with the arm 40 and actuated from the incline 32, I employ a quadrant-operato r 3h, which preferably consists of a crooked lever :l'ulerumcd on a shaft or axis A fixed on the frame A for action,substantially as indieated. The rear end of the lever 38 is connected to the hub of the arm, 40 by a chain 39 or in other equivalent manner, while its forward end works in conjunctimi with the adjustable inclined guide 32, itbeingpreferably provided with an ft-lllllltl'lCtlt'jll traveler or shoe 3t that slides in the guideway thereon. \Vhcn the carrier bar 10 moves forward, the inclined guide lifts the forward end of the quad rant-operator lever 38, causing the arm it) to swing l )ackward, as indicated in dotted lines, Fig. 4:. Then, when the carrier bar moves backward, the quadrant operator moves down the inclined gnideway and permits the quadrant-arm 4-0 to again swing forward. The guidcway 3'. is best provit'lcd with an oil-well 237 at its lower end, as shown in lfig. 7, into which the end of the shoe 3t dips when at its lowest position and from which it carries up, as it moves back along the guide, a quantity of oil sutlicient forlubrieating the surface on which said shoe travcls. The winding-chain it is attached, at one end to the \\'ii1dingli.'uin (1 on the cylinder-shaft (1. It then passes around the pulley it on the quadrantarm, thence around a pulley d running on a stud fixed to the roving-beam l), and thence extends to and is attached to the upper end of the quadrant-arm.

The end of the winding-chain is attached to the upper end of the quadrant-arm by an adjustable st-ud at 42, by means of which the tension for winding the nose of the bobbin can be increased or diminished. .lly earrying said stud farther from the axis on which the quadrant-arm swings the mechanism is caused to wind the nose of the bobbin tighter, and by carrying said stud nearer to the axis the mechanism is caused to wind less tight.

\Yhen the roving-beam l) approaches the spindles, the quadrant-arm,with the pulley i], swings forward, releasing the windingehain, the degree of such release being governed by the action of the quadrant-operator in conjunction with the adjustable inclined guideway and adjusting-shaft of the copbuildcr mechanism.

The chain 3i), which connects the quadrant arm and operator lever, is provided with an adjusting hook or link 3!), the shank ofwhich is screw-threaded and connected with the lever in a manner to facilitate the lengthening and shortening of the connection, so that the parts can be relatively adjusted to ecumensate for wear, for the stretch of the chains by use, or for bringing the parts into proper relation when setting up the machine.

The ratchet-wheel 27 at the end of the adjusting shaft it is interchangeable with wheels having different numbers ol:' tceth for s iinning different numbers or sizes of yarn, said wheels varying in their numbers of teeth from eight to thirty, (more or less,) as de- ITO sired, the lesser number of teeth being employed for the coarse sizes, while the greater number are employed for the fine sizes of yarn.- The screw-shaft 14 controls both the cop-builder and the winding mechanism; hence the simple change of the ratchet-wheel 27 is all that is required for adapting the copbuilder and winding devices for working any of the various sizes of yarn which it is desired to spin, and thus the cop-builder devices and the windin g devices will properly and proportionately coincide in their relative action under any and all circumstances. This is a very important feature, which, so far as I am aware, has never before been attained in any spinning-machine wherein backing off and winding is a part of the operation.

By combining the cop-builder mechanism with the quadrant and winding mechanism, so that both are simultaneouslycontrolled by the same adj Listing-shaft or screw-spindle, as herein set forth, I attain the advantage of a positive uniformity of operation on different.

sets ofbobbins and allnumbers of yarn, since the ad j ustment and regulation of the quadrantoperating devices are automatic and positively in unison with the adjustment and regulation of the cop-builder, either when moving inward or while being returned to starting extended and fitted to carry a toothed segment 391, that meshes withatoothed segment 401, formed on or attached to the hub of the quadrant-arm 40. The segment 391 can be made longitudinally adjustable by screws 381, or otherwise, so as to bring the arm 40, and operator-lever 38 into proper relationwith reference to the inclined-guide 32 and winding-chain 44. In Fig. 26 I have illustrated a manner of connecting the quadrantarm 40 and operator-lever38 by achainfrom the forward end of said operator-lever. In this the chain 39 is fixed to a stud 392, that is adjustable in a slot at forward end of the operator-lever, and from thence passes beneath a guide-sheave 383, fixed to the stationary bed or frame, and up to the hub of the quadrant-arm 40. In each of these modifications the inclined guide 82 imparts similar action to the arm 40 by the reciprocation of the cop-builder carrier 10.

Another feature of my invention consists in an automatic take-up which acts on the Winding-chain 44 and serves for effecting the tighter winding of the yarn upon the nose of the bobbin. This mechanism (see Figs. 2 and 19) consists of a swinging lever 46, carryin g at its lower end a sheave or guide-pulley 47, over which the winding-chain 44 passes, while its upper end is connected to an actuating-bar 48, which is furnished with an inclined ratchet or series of notches or steps 481, for engagement with a detent or lug 49, that is fixed on or connected with the roll-beam D. The forward end of the actuating-bar 48 is sustained by a stud, roll, or bearing on the arm of a lever 50, that is centrally fulcrumed on a suitable support-bracket or projecting part of the frame A, the other end of said lever being c011- nected by a chain or link 51 with the rear end of the cop-builder arm X, or, preferably, as in the present instance, to the end of a spring-bar 52, attached to said cop-builder arm, as indicated in Fig. 19. Depression of the rear end of the cop-builder arm as it follows the action of the builder-bar mechanism effects a corresponding elevation of the ratcheted end of the actuating-bar 48, causing when at suflicient height its engagement and movement to a greater or less extent with the detent 49 on the roll-beam D. hen the detent 49 engages the bar 48 and carries it forward, the lever 46 lifts the pulley 47 against the chain 44 and causes an extra pull or strain on said winding-chain (see dotted lines, Fig. 19) and a quickened action of the spindles the instant the yarn is being wound on at the extreme point or nose of the bobbin, thus tightening the winding of the yarn at such point. Vhen commencing and while filling the body of the bobbins, the bar 48 is depressed so low that its ratcheted end is not engaged by the detent 49, the parts being ordinarily adjusted so that this mechanism is brought into action only for the completion or final finishing of the bobbins.

Another feature of my invention comprises the improved mechanism for easing in the roving-drum carrier or roll-beam D to accommodate the shortening of the strands of yarn by the twisting. For this I employ a wormgear 54, mounted on a swing-bracket 541, having a spring-bar 55, which works in conjunction with a cam 551 on the cam-shaft I for raising said wheel into mesh with a worm 56 on the shaft K Said worm-wheel has attached to its side or to the opposite end of its axle-stud a crank which is connected by a chain and rod 57 with a balanced lever 58, mounted upon a screw-threaded hub 59, fixed on the back shaft B. (See Figs. 3,12, and 13.) The lever 58 is counterweighted 'at its rear end, as at 60, to lift the rod, chain, and crank and to return the worm-wheel 54 to normal position when it is thrown out of engagement with the worm 56. Upon the side of the lever is a pin or lug 61, that engages at the proper time with a stud 62 on the side of the auxiliary scroll M, or, if in any case preferred, said stud can be upon a separate disk or arm fixed to the back shaft B in lieu of the side of the scroll.

manner that rotation of the shaft B causes a movement of the lever longitudinally upon shaft B toward and from the auxiliary scroll. (See dotted lines, Fig. 12.) This movement is The hub of the lever 58- is screw threaded and fitted to the hub 59 in such ICC IIO

Lin

suffi cient to bring the lug it into engagement with the stud H2 when the rope j is wound upon the draftscroll .l and to carry the parts away from each other, so that the lug til escapes the lug (52 at other revolutions of the back shaft 13. The operation of casing in is effected at the time the lugs are brought into engagement with each other, at which time the worm-wheel 54 is in mesh with the worm 5f, it being lifted up by its arm in contact with a cam on the cam-shaft. The action of: the crank on the worm-wheel draws down the connecting-rod 57, depressing the forward end of the lever 58 and lifting the lug 01 against the lug U2, thereby causing slight forward rotation of the back shaft 13 sufticicnt to move the roll-beam 1) forward as the yarn shortens by twisting and previous to the ind rawing movement for winding up the spun yarn. The lever 58 is preferably slotted, as at ('33, (see Fig. 13,) to facilitate the adjustment of the stud 01, so that it will engage with the stud (J2 at the proper instant. The connection-pivot it at the forward end of the lever is made adjustable toward or from the fulcrum, thus affording facility for varying the extent of the easing-in action by varying the leverage so that the stud (it moves in a longer or shorter arc. The rod 57 isbestprovided with a screw-threaded extension or turnbuckle to facilitate lengthening or shortening the connection.

The clutch forconnecti ng the win ding-drum to the cylinder-shaft is substantially as heretofore employed; but the means for producing friction for winding up the chain upon said drum is a feature of my present invention. Upon the auxiliary shaft Q, below the cylimler'shaft t, I arrange a pulley 70, from which a belt 71 is carried around the wind ing-d rum C, and mounted on said auxiliary shaft is a loose swinging lever 72, one arm of which is provided with a pulley 73, which runs against said belt 71 fortighteningit upon the drum audits pulley, while the other end. of the lever is provided with a counter-wcight7t for pressing the tightener-pulley against the belt. The counter-weight- H is given enough pre ponderance to cause friction of the belt on the drum sufficient to wind up chain 411- when the roll-beam moves backward, butnotcnough to prevent the drum slip iing within the belt by the draft on the chain it when winding the yarn.

To the side of the falter-lock I is pivoted a backwardly-extending bar To, the rear end of which is in position to engage the lug 761 on the escapcment-lever I. when the faller-lock is drawn back under the roll X of the copbuildcr arm X. Projecting from the side of said bar is a lug or pin 73, which is engaged by a plate 79, adjustably .tixed upon the side of an upright lever 50, thclower end of which is pivoted to the bedframe at 81, while its upper end is in position to engage with a lug or arm that projects from the roll-beam orits shoe when at its forward position. 111 its forward movement the roll-beam strikes the up per end of said uprightlever to throw off the taller-lock I! from the roll X at the instant the rollbeam reaches its forward position. The plate 71] upon the lever 80, which engages the lug 7b, can be adjusted for caitsing the :faller-lock to be thrown off at the proper .instant of time. The backing-off clutch 82 and falter-lock chain are of the usualconstruction and are arranged to o 'ierate in the well known manner. The drawing up of the chain 83 and locking of the falkw-lock on the roll X" of the eo1 )-buildcr arm X force back the cscapement-lcver L by means of the arm T and throws thelug]: off the escapcmcnt-wheel ratchet, at which time the action of the camshaft 1 brings into ODOt'tt-tlOll the iii-drawing scroll and winding mechanisms.

For preventing the counterfaller f from rising while backing oil? and while the rollbeam 1.) is at rearward positionl employ a device which consists of a lever 85, fulcrumed at so to a suitable bracket or support on the frame of the machine and having its forward end connected by a cord or chain 87 with the counterfallerf, said chain being passed under a guide-sheave 9 as indicated in Fig. 27. The rear end of the lever s5 is shaped with a suitable cam or inclinedsurface, which is engaged by the roll-beam l), or a detent attached thereto, when said roll-beam is at baclnvard position, thereby holding the lever depressed at its rear end and causing the consequent elevation of its forward end, which draws down the chain passing beneath the sheave, so that the counter-taller is positively held depressed so long as the roll-beam .I) is in contact with the lever; but when the rollbeam a iproaches the spindles said lever is freed and the counter-falter is released for doing its work while winding the yarn on the bobbins.

The clock or indicator J5, for denoting the runs of yarn, may be of any suitable construction. In the present instance it comprises a rotating graduated dial 951, mounted within a suitable case on a vertical axial stud and provided with gear-teeth that engage with a worm-screw 952 on a horizontal arbor furnished with ratchet mechanism, whereby motion imparted to the dial. An irulcx-point J53, tixed on the case, extends onto the graduated circle for denoting the degree of movement of the dial. Said clock is mounted upon the roll beam or carrier over one of the guideways a, on which said roll-bean1 travels, and is operated by means of a ratchet and pawl 96, the pawl being connected with a bar 97, to which movement is imparted by an incline or cam surface 38, formed in the uide a, (see Fig. 28,) into which the end of the bar )7 drops when theroll-beam approaches thelimit of its forwardmovement, andis subsequently lifted as the roll-beam moves backward, so that the pawl is actuated for operating the indicator mechanismv one step (more or less) at each backward movement of the roll-beam IOC.
